• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang ((((x hoi) OR (xa hoi))) or (x ho)). hieu quan cau truc va hanh vien cac tro~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang ((((x hoi) OR (xa hoi))) OR (x ho)). hieu quan cau truc va hanh vien cac tro.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang ((((x hoi) OR (xa hoi))) or (x ho)). hieu quan cau truc va hanh vien cac tro".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang ((((x hoi) OR (xa hoi))) or (x ho)). hieu quan cau truc va hanh vien cac tro*.
